General relativity, which describes gravitational interactions in terms of space-time curvature, has made great achievements in explaining many kinds of gravitational phenomena at various scales. Despite its success, however, general relativity still faces some theoretical challenges. One problem with general relativity is the existence of spacetime singularities in the solution of Einstein's equations. The Singularity theorem[1]} guarantees that the formation of singularities is a general feature of gravitational collapse. At the singularity, the physical quantities diverge. To ensure that there are no naked singularities in spacetime, Penrose proposed the weak cosmic censorship conjecture[1]}, [3]}.
